Mortality rates vary depending on socioeconomic differences among areas in Europe

For a number of years now, scientific literature has questioned whether mortality rates depend on socioeconomic differences among the population. Recently, a new study carried out in 15 European cities - including Barcelona and Madrid - detected inequalities for the majority of causes, concluding that higher levels of poverty are associated with higher mortality rates and there is a great deal of variation among areas.

1 in 4 people with histories of nicotine use, substance abuse likely to use opioid painkillers long-term

Opioid painkiller addiction and accidental overdoses have become far too common across the United States. To try to identify who is most at risk, Mayo Clinic researchers studied how many patients prescribed an opioid painkiller for the first time progressed to long-term prescriptions. The answer: 1 in 4. People with histories of tobacco use and substance abuse were likeliest to use opioid painkillers long-term.

Study sheds new light on how the brain forms memories

In the first study of its kind, UCLA and United Kingdom researchers found that neurons in a specific brain region play a key role in rapidly forming memories about every day events, a finding that may result in a better understanding of memory loss and new methods to fight it in Alzheimer's and other neurological diseases.

Scientists develop implantable 'artificial pancreas' to help control blood sugar in diabetes patients

Living with Type 1 diabetes requires constant monitoring of blood sugar levels and injecting insulin daily. Now scientists are reporting in the ACS journal Industrial & Engineering Chemistry Research the development of an implantable "artificial pancreas" that continuously measures a person's blood sugar, or glucose, level and can automatically release insulin as needed.

Eating at full-service restaurants not necessarily healthier than eating at fast-food outlets

When Americans go out to eat, either at a fast-food outlet or a full-service restaurant, they consume, on average, about 200 more calories a day than when they stay home for meals, a new study reports. They also take in more fat, saturated fat, cholesterol and sodium than those who prepare and eat their meals at home.
